About SnapShot...

[julitobatata]

I am trying to save some frames samples from a video without starting to play. How can I do that?

Actually I can render to FBO in my Qt application without problems. But, when I try to take a snapshot the result is a black image. Do you have some example to show how can I do that?

Do you have a minimal example?

The first snapshot will be omitted. You have to add a dummy snapshot.

    Player::SnapshotRequest req{};
    player.snapshot(&req, nullptr);
    player.snapshot(&req, [](Player::SnapshotRequest* r, double t){
        printf("snapshot.jpg\n");
        return "snapshot.jpg";
    });
